Answer:
B) hyperbaric oxygen chamber to increase PO2 and clear CO from the body
Explanation:
Carbon monoxide poisoning occurs from the breathing in of poisonous gas, carbon monoxide (CO) at high levels. Large exposures of the gas can result in the loss of consciousness, seizures, or even death.
<u>Hyperbaric oxygen is used in treatment of carbon monoxide poisoning, as it hasten the dissociation of CO from carboxyhemoglobin and also cytochrome oxidase to a greater extent as compared to normal oxygen. It also enhance the oxygen transport to tissues by the plasma.</u>
The correct answer is to replenish carbon dioxide needed by plants
Hope this helped!
Good luck :p
Brainliest is appreciated <3

When we say STP that means the system is at its standard temperature and pressure. Both systems is having the same condition hence temperature and pressure is constant. We then set the amount of gas in both cases to be equal. Hence from the ideal gas law,
PV=nRT we can say that with everything constant, volume must also be constant.
The answer is (2) 2 L of methane gas.
Answer:
a. absorbs energy as heat and has positive enthalpy of solution.
Explanation:
A reaction can either be exothermic or endothermic. An endothermic reaction, as the dissolution described in the question, is that which absorbs heat energy from the surroundings in order to start the reaction.
Because an endothermic reaction makes heat lost from the surroundings, the enthalpy (∆H) of the solution will be positive (+). ∆H is got by finding the difference between the enthalpy of the reactants and products and since the enthalpy of a product in endothermic reaction is more, the enthalpy change (∆T) will be positive.
